HENRY SCHURR, 0E PHILADELPHA, PENNSYLVANIA.

` CAB-FENDER.

To all whom' tA may concern Ile it known that I, HENRY boi-mine, a

citizen of the United States, residing at lliila ,lelpliia, in the county oil? Philadelphia and State oli Pennsylvania, have invented certain new" and useful Improvements in Car-Fenders, ol which the 'following is a specilication.v Y

Numerous types of car fenders have been made prior to my presentinvention in which va main catch ienderis lowered due to the trippingofa gate by a" person or object en the track. However, the structure has been such. that very oftenA vthe catch or main 'Fender permitted the objector person to be l proximity to the rground or bed of the track and when once lowered will elliciently serve to prevent a person or object from being wedged thereunder or permitted to pass between the main fender and the'roadbed.

Another object is` to provide a fender which will be of a practical and durable construction and which can beeasily re-set by a motormaii so that it will automatically operate as'above described.

A still further object is to so construct my improved fender that vwhen once the trip gate is tripped that the main or catch fender will be projected into a flat position close to the surface of the roadbed and will positivelyremain in said projected position uutil it is re-set.

These objects, and other advantageous endswhich will be describedhereinafter, I attain in the following manner, reference being had to the accompanying drawings in whichy Y j rFigure 1 is aside elevation showing my improved `fender attached. to a car,

Fig. 2 is a fragmentary sectional elevation of my improved fendery showing the parts in theirnormal position. j

Fig. 3 is a lView of similar character to Fig. 2 showing the parts inra-n operative position having been automatically moved due to the tripping of the trip gate, y

Figa is a front elevation of Fig. 3,

specification of Letters Patent. Patented June 22 1920 l Fig. 5 1s a fragmentary plan view partly 11i section,

il* ig. 6 is a sectional elevation of one form ot re-setting mechanism which l preferably employ, andv y. l* ig. 7 is ya fragmentary sectional plan view taken on the line 7--7 of Fig. 6.

lxefeiring to the drawings8 represents a car, such for example as an' electric street car, which runs on a track 9 and which has a bottom frame 1() supporting a platform 1l. Two vertically disposedcylinders 12 have their upper ends closed by heads 13 and these cylinders and heads are secured to the `frame l() by bolts 14.' The heads 13 have sleeves 15 which depend into the tops of the cylinders, as clearly shown in Figs. 2 and 3. The lower ends of the cylinders are provided with caps 15l which are screwed therewhichhave'screws 17 extending into the caps. rlllie plates `1G are pivotally rmounted Y on; saidcaps being supported by plates 116 on the lower ends of braces 18; said braces,

as shown in Fig. 1, being secured at their upper ends to the -frame 1() of the car.

Two yokes 19Y are provided and each of these yokes has an arm 20 which extends under one of the plates 16 and another arm 21 which extends through an opening 22 into a respective cylinder 12; said arm 21 serving as a piston for lowering a main or catch fender as will hereinafter be described.` A coiled spring 23 isinterposed in each of the cylinders 12 between the head 13and the piston arm 21. A guidepost or plunger 24 extends vertically through each ofthe cylinders 12 and through holes in the arms 20 and 21. A shoulder 25 is provided on each of the posts 24 for engagement with the -lower face ofthe piston arm 21.

The lower ends of the posts 24 have heads 26 for engagement with the lower surfaces of the respective arms 20. The upper end portions of the posts 24 are slidable within the respective sleeves 15 so that the springs 23 are capable, under certain conditions, of moving the yoke 19 from the position shown in Fig. 2 to the position shown in Fig. 3. The upright portions 27 of the yokes 19 are bolted or otherwise secured to a vertical extension 29 onthe main or catch fender 29; said main or catch fender being made of skeleton vframe work and having its base portion 30 positioned parallel with theV track or roadbed 9. The portion 30 of the `fender i 29 has an open flexible net portion 31 secured above vit and the forward portion of the fender 29 is preferably arched or rounded as shown at to provide a flexible buffer.

By making this fender in the above described manner a light weight structure is provided which is sufliciently open or per- .forated to permit any snow to fall therethrough to the street. A shaft is ro tatably mounted in hanger bearings 34 which are secured to the bottom of the car frame 10 and this shaft 33 has two winding drums secured thereto; said winding drums `having ends of chains 3G secured thereto; the other ends of said chains being secured tothe vertical extension 23 of the main or catch fender 29; the arrangement being such, as shown in Figs. 2 and 3, that the chain `extends substantially tangent from the forward face of the vertical extension 28 to the peripheral faces of the winding drums 35. i

A retaining rod v37 has its omosite ends secured to the winding drums 35 and an arm 33 of a bell crank lever 39 normally rests on the retaining rod 37 and has a detent head 40 in the form of a hook`which 4cngaglgjes or embraces the rear portion'of the retaining rod, as shown in F ig. 2. The bell crank lever 39 is pivotally mounted at 4l to a bracket 42 which is secured to the bottomof the car frame 10. Y

A spring 43 is mounted in afhousingl in the frame l() and surrounds the stem 45 of a pressure shoe 46; said pressure shoe being in engagement with the top ofthe arm 38 kand serving to hold the detent head el() in embracing position with the retaining rod 37 when the parts are in their Vnormal position with the spring 23 compressed and the yoke 19 and main or catch fender 29 raised. je; -slide rod -17 is supported between rollers '19 in the bracket l2 and rollers i9 in a bearing 50V; said bearing 50 being secured to thc under part or the car frame lll. A rock shaft 5l is mounted iu the lower end of the hanger bearing 50 and to this rock shaft secured a trip gate 52; said trip gate normally' depending in a vertical position as shown in Fig. 2 and being made or screening 53.

A collar is secured to the rock shaft 5l and has a weight 'and a lug cam 5G of a frame work having a liexible netting projecting` therefrom; the lug cam being Y 47 and the slide rod will be moved for-4 wardly so as torrock the bell crank lever 49 so as to lift the detent head 50 out of engagement with the retaining rod 37. The retaining rod thus freed will permit the spring 23 to expand and move the yoke 19 and main or catch fender 29 downwardly in a vertical path into close proximity with the track or roadbed.

A stop rod has its opposite ends secured to the winding drums 35 and this stop rod is located at a greater distance from the shaft than is the retaining rod 37. Thus the stop rodr 6() will engage the raised detent head 40 and thereby limitl the downward movement of the main or catch fender, as clearly shown in Fig. 3. lVith the construction as illustrated and as above described it will be -noted thata positive .vertical movement is imparted to the main fender and the main fender remains in a substantially parallel position at all times with the track or roadbed. Furthermore it is practically impossible with the structure as above described for anything tolft the main fender by engagement withA the forward end thereof, since in sodoing a leverage would be imparted which would tend to jam the parts within the cylinders and thereby prevent them from being accidentally raised. It will he noted that any object falling on the track in front of the ear will engage and swing the `trip gate from the'position shown in Fig. 2 to the position shown in Fig. 3 and therefore will release the mechanism topermit the spring 23 to `act as above described. n

In order to re-set the main fender 29 after having been automatically operated I provide the shaft with a bevel gear 61 which meshes with another bevel gear G2 on an upright shaft G3. Said shaft maybe similar to an ordinary brake shaft and is provided with a ratchet 64 directly above the platform 11 and a pawl .or dogI 65 is mounted on the platform and is so constructed that it will release unless held against the ratchet 64. The upper end `of the shaft 63, as clearly shown in Figs. (3'

and 7, is provided witha head 6G which is slotted transversely as shownv at 67 and is also provided with a vertical notch 68.

A handlever G9 has a slot 70 adjacent one end and a 4pin 7l extends through the head G6 and through the slot 70. The pin 71 is positioned to i.extend transversely across the slot`67 of the head and above the notch (38 so that normally the hand-lever 69`can be positioned vertically as shown in vfull lines in Fig. 6 and can be lifted and swung into the slot 67 when it is desired to rotate the shaft 63. When it is desired to rotate the shaft, the hand-lever 69 can be lifted until its lower end frees the notch 68 after which it can be swung into the slot 67 of the head and the shaft 63 can be partially rotated and the pawl 4or dog 65 canbe pushed into engagement with the ratchet 64 and held f there until the hand-lever hasbeen swung into an opposite position from that shown in dot-and-dash line, after which the shaft 63 can be again turned a part of a revolution. With this construction the shaft 63 can be placed close up to any partition or the front or side of the car and will not take up a great amount of room. It will be noted that kwhen the shaft 63 is thus turned the geared connection will turn the shafty 33 and drums 35 clockwise until the retaining rod 37 engages under the detent head 40 and passes into a position to permit the detent head to again embrace the retaining rod 37A and thereby hold the parts in their set positions.

I preferably curve the detent head 40 as shown at 72 so as to permit, during the re-setting operation, Athe retaining rod 37 to engage under and lift the detentyhead 4() against the action of the spring 43 until the retaining rod has passed thereunder, after which the spring 43 will move the detent head 40 downwardly into the embracing position as above described. The

trip gate 52 after having been moved rearwardly will again swing into its normal vertical position and this action is assisted by the provision of the weight 55 as above described.

The piston arm 2l of the yoke 29 is preferably in screw threaded connection with the lplunger or guide post 24 and if it is desired to remove the parts for any vpurpose whatever, the plunger can be unscrewed and the plate 16 can be released from the cap 15 by removing the screws 17 after which the plate v16 can be swung into a vertical position and the cap 15a can be unscrewed from the cylinder 12. It can then be removed and if desired the spring 23 can be removed from each of the cylinders.

The structure of my improved fender is ksuch that it can be placed upon practically allV cars without materially changing the latter and can be easily regulated to suit various requirements.

IVhile I have described my invention as taking a particular form, it will be understoodthat the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that 'I am at liberty to make such changes'and alterations as fairly come within the scope of the appended claims.v
